That was my assumption as well as
Confirmed by JimsCAL and yourself.
I have tried in vane to identify this transducer. I haul out
in a month and perhaps that will assist me.
I can find no identifying numbers visible.
What I pondering at this point is wether or not it would have to be close to the Raymarine
200khz to even put out bad readings. My thoughts being that if it’s getting some kind of response with the 200khz impulse it would need to send/receive it at the transducer in some way. I have read that 210khz and 160khz transducers exist and this would be a smaller range than “no idea”.
My goal is to find a head
unit I can purchase
second hand that will interface with the RCA transducer.
